Q

What is electrical charges?

A

Each proton carries a positive charge and each
electron carries a negative charge. Protons are held tightly in
an atom’s nucleus, but the electrons can be transferred from
one atom to another. Negatively charged bodies have a
surplus of electrons (more electrons than protons) and
positively charged bodies have an electron deficiency (less
electrons than protons).
